Systems and methods for user authentication in video communications

A system comprising:

• one or more processors;
• and
• a non-transitory computer-readable medium storing instructions that when executed by the one or more processors, cause the one or more processors to perform the operations including:
• receiving one or more video frames from a video communication session between a first user device and a second user device, wherein at least one video frame of the one or more video frames includes a representation of a user of the first user device;
• extracting, from the at least one video frame, a set of features associated with the user of the first user device;
• executing a neural network using the set of features to generate a first depth map of the user of the first user device;
• authenticating the user of the first user device based on matching the first depth map with a second depth map associated with an authenticated user;
• and
• generating, in response to authenticating the user, a third depth map by merging the first depth map with the second depth map, the third depth map being usable to authenticate the user of the first user device during a subsequent video communication session involving the user.
